Firefox developers Mozilla, are announcing the release of Firefox 40 today. Despite Mozilla’s open objections to Windows 10 as well as its shrinking presence in browser market share, Firefox 40 comes with support for Windows 10, Mac, Linux, and Android. According to Mozilla, “half a billion people around the world” use the browser. With FireFox 40, users will benefit from added protection against unwanted software downloads, interface changes as well as new gesture controls for navigation on Android devices.
As for PCs and Windows 10 support, earlier versions of Firefox worked on Windows 10, however, Mozilla is officially announcing support for Windows 10. Aside from the semantic wordplay from Mozilla, Firefox 40 does come to Windows 10 with a few subtle differences. While Mozilla claims users will notice, “bigger, bolder design elements,” many of the changes seem rather subdued in Firefox 40 for Windows 10. New tab and tab close buttons have been visually updated and enlarged; other icons have darkened.
In addition to visual tweaks, Firefox 40 also improves on back-end security and performance issues. With Firefox 40, Mozilla will now require all Firefox add-ons be certified, regardless of where they are hosted. Users will also be warned about unsigned add-ons starting with Firefox 40. Mozilla hasn’t stopped there, with Firefox 41 Mozilla has worked with developers to meet better security concerns by disabling extensions that have not met certifications and enabling preferences for disabling signature enforcement. According to Mozilla, Firefox’s 42 beta and release versions will not allow unsigned extensions to be installed and users there is no way to override this.
